Request fail on parsing json body with accent character

[oliviercperrier]

I am calling an endpoint i made to update a customer. When passing my json body i get a 400 Bad request. Seems like a json body that contains accent characters is not parsed correctly by the request object.

Note: when using flask without awsgi like so:

@app.route('/', methods=['POST'])
def test():
    return request.get_json()

everything is working, but when i use awsgi:

def lambda_handler(event, context):
    return awsgi.response(app, event, context)

@bp.route('/<id>', methods=[METHOD])
def update_customer(id, query_params={}):
    return request.get_json()

This throw me a BadRequest error and the error is on get_json.

I don't really know what awsgi is doing with the json body, but something is done incorrectly.

Environment

• Python version: 3.7.4
• Flask version: 1.1.1
• Werkzeug version: 0.16.0

Hi, @oliviercperrier. Thanks for reporting this issue.

Can you provide a list of steps to reproduce the issue? Without a sample of the response body or any demonstration, I don't think I'll be able to troubleshoot this.

Thanks!
